is a fragmentary detail view, showing a plan of one of the guide membersfor the locking joints, and Fig. 7 is a detail sectional view on theline 77 of Fig. 6.

Referring in detail to the drawings by numerals, 1 designates the basemember and projecting upwardly from the opposite corners of the base 1are the standards 5 which are connected at their upper ends by thesemi-circular frame member 6 above the semi-circular base member 1.

It will be understood that the base 1, and parts connected therewith, asdescribed above, may be formed of metal, c s shown, or of any othersuitable material.

Positioned at the center of the semi-circular base member 1 andextending upwardly are the hollow tubular members 12 which arepreferably parallel to one another and positioned one forwardly of theother, as clearly shown in the drawings. The central portion of theframe member 6 is secured between the tubular members 12, adjacent theupper ends thereof. The outer or rear tubular member 12 is provided witha longitudinal elongated slot 13 extending preferably its entire length,and the purpose of. which will presently appear.

The opposite ends of the substantially semi-circular frame member 6 areconnected by the transverse bracing bars 14, and the transverse bracingbar 14; carries the braclo ets 16. The lower sections 19 are pivoted at20 to the upper sections 21 and are provided with the reduced bentextremities 22 for engaging in the locking recesses 23 in the saidsections 21 to limit the movement of said sections 19 and 20 in onedirection and lock said sections in alinement.

v to one of the brackets lock or knuckle The lower free extremity of thesection 19 of each lock or knuckle joint 20 is pivoted 16, while theupsection 21 of each joint 20 is rigidly mounted upon the shaft 24secured transversely through the upper end of the outer verticallymovable post 25, it being understood that two posts 25 are provided andslidably or telescopically engaged in the tubular members 12, said posts25 being of such length that when in their lowermost position, the upperends thereof project above the upper open ends of said tubular members12. The lock or knuckle joints 21 are resiliently retained-in normal orlocked posiperfree extremity of the 7 tion by means of the helicalsprings 26 which have their lower ends secured to the frame member 6 inany suitable manner, while their upper ends are secured to the lower sections 19 of said lock or knuckle joints 20,

adjacent the upper ends thereof, as clearly shown in Fig.

3. Sectional joint breaking arms 27 are also pivoted to the lowersections 19 of thelock or knuckle joints 20, adjacent theupper endsthereof, and also pivoted to the levers 28 employed for operating thejoints breaking arms 27, as will be later clearly understood.

The levers 28 are positioned upon opposite sides of the forwardlyextending horizontal V beam 29 which'is mounted at its rear end upon-theupper ends of the vertically movable posts 25, previously mentioned,it'being understood that the beam '29 is provided with suitable openingstoaccommodate said p s movement of the outer post 25 V through the'beam29'being prevented by the beam 29 is prevented rigidrwith the verticallvshaft 24,-

previously mentioned, and which extends transversely through the beam 29as well as said outer post 25. Movement of the forward or inner post 25through the by the fastening mem- -ber -30'iengaged transversely throughsaid beam 29 and said forward orinner post 25, as clearly shown-in thedrawings. It will therefore be seen that the beam 29 isheld v movableposts 25 r and extends forwardly-from the same, the

main portion of said forward or free'end of said beam extending over thecenter of the mixing'vessel 4.

The levers 28 are, pivoted intermediate 3 5 their ends upon the pivotpin 31 extending transversely through the I forward portion of the beam29 and said levers are adapted'to be swung upon said pivot pin in onedirection, by means of the operatingrods 32 which are pivoted at oneendto. the free ends of said levers 28 and connected at their oppositeends; to the arms right angles to the same,said members 33 be operatedby the operating handle 34 which is connected to the member 33, by theconivessel 4 from the beam 29 and parts of the U-shapedmember shaft '24and extending at necting bar 35. The member 33 is resiliently retainedin normal position by the helical spring 36 which has one end connectedwith the free end of said member 33, while the opposite end of saidspring is connected with the bracket 37 secured to the beam 29, a spaceddistance from the free or forward end thereof.

After the mixing vessel 4 has been placed in position upon the basemember 1 and base extension 2, the handle 34 is pressed downwardly toswing the member 33 and shaft 24. This will draw rearwardly theoperating rods 32 and thereby swing the levers 28 upon the pivot pin 31to cause the sectional joint breaking arms 27 to pull up wardly andforwardly upon the upper portions of the lower sections 1.9 of said lockor knuckle joints 20, against the tension of the springs 26, therebybreaking the joints and allowing the beam 29 and rods 25 to movedownwardly by gravity owing to the weight of said beam 29 and rods 25and the parts carried thereby. This downward movement of the parts willplace the mixing member proper 38 mounted upon the shaft 39, in properposition in the center of the mixing vessel 4. The shaft 39 is rotatablymounted in the sleeve 40 positioned vertically through the forward freeend of the beam 29 and said shaft 39 and mixing member 38 may be readilyrotated by operating the handle 41 upon the stub shaft 42 positioned ina suitable bracket 43 also carried by the beam 29, said stub shaft 42and the shaft 39 being connected by intermeshing gears 44 and 45 carriedby said shafts 42 and 39 respectively.

When it is desired to remove the mixing upon the base member 1 and baseextension 2 and the supporting bars 11 connecting same, it is simplynecessary to press downwardly the enlarged or handle end 50 of theraising lever 51, which is fulcrumed intermediate its ends upon thefulcrum pin 52 extending transversely through end pivotally connected tothe semi-circular base member 1. By moving the lever 51 in this manner,the free end thereof mounted upon the bolt 54, will be forced upwardly,thereby forcing the bolt 54 to move upwardly in the guide slot 13 of theouter or rear tubular member 12 and as said bolt 54- is secured in therear or outer post 25, both of the vertically movable posts 25 as wellas mounted thereon will be forced to move upwardly to the position shownin Fig. 3, when the lock or knuckle joint sections 19 and 21 will bebrought into alinement and thereby cause said joints to automaticallylock and prevent downward movement of the parts without operation of thehandle 34 and U-shaped member 33, as

previously described, to break the joints 20. Further it will be readilyseen that as the lever supporting member 53 is pivoted at its lower end,said member will readily swing upon its lower end, during operation ofthe lever 51 in either direction.

While I have shown means for raising and automatically locking in raisedposition, the rotary member or mixer proper of the mixing machine andincluding novel means for releasing the locking means to allow the partsto descend to normal position, it will be understood that this mecha-'nism may be employed in connection with various other machines and istherefore not limited to use in connection with mixing machines and thelike.

While any suitable form of mixing member 38 may be employed, 1 haveshown a mixing member 38 consisting of a stem 56 having itsupperextremity adapted for removable engagement with the shaft 39, whilethe main portion of said stem 56 has mounted thereon a substantiallyrectangular agitating member 57 which is preferably locked for rotationwith the stem 56 by nuts 58 or the like threaded upon said stem andbearing against the upper and lower longitudinal portions of saidagitating member 57. Within the agitating member 57 and loosely mountedupon the stem 56 are a plurality of substantially triangular agitatingmembers 59 of different sizes and adapted for independent rotationwithin one another. VVithin the smallest or inner triangular agitatingmember 59 is a substantially small agitating member 60 of substantiallyoval form which is also loosely mounted upon the stem 56. It will beunderstood that the lower portion of each agitating member is preferablyspaced above the corresponding portion of the agitating member withinwhich the same is positioned, to permit free rotation of each and everyagitating member. It will also be understood that the upper portion ofeach substantially triangular agitating member 59 is preferablyflattened and thereby increasing the width of the upper ends of saidagitating members 59. Upon rotation of the shaft 39 to revolve the stem56, all of the agitating members carried by the latter will be caused torotate freely and thereby thoroughly agitate and mix the contents of themixing vessel 4:, as will be readily understood.
